Serial No. 505,250.

To all whom it may concern:

Be it known that I, JOHN P. NAWN, a citizen of the United States, residing in Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Tater-Regulators for Gas-Producers, of which the following is a specification.

My invention relates .to that class of devices wherein water is admitted to a gas producer to enrich the gas by means of the decomposition of water into its constituent elements, hydrogen and oxygen, the oxygen serving to form incomplete combustion of the carbon of the fuel and the hydrogen be ing given off as a free gas of a highly explosive nature; the amount of water admitted being dependent upon the demands of consumption from the producer, and my objects are; first, to provide means whereby the amount of Water may be automatically regulated to the gas producer dependent upon the demands for gas therefrom; sec- 0nd, to provide additional adjustable means which can be operated manually for regulating the amount of water to said producer; third, to provide an auxiliary means for admitting water to the producer air pipe when the demands for water would be abnormal; and fourth, to provide means to prevent the head of water in the water supply pipe to the air pipe from interfering with the automatic regulation of water to the gas producer upon normal demands for Withthese objects in view my invention consists in certain novel features of construction and arrangement of parts as will hereinafter be more fully described and pointed out. in the claims, .reference being had to the accompanying drawings, forming part thereof and, in which Figure 1' 1s a sectional elevation of a gas producer air pipe showing a convenient embodiment of my invention as applied thereto; Fig. 2 a plan viewv of the same; Fig. 3, a sectiona elevation of a water pot and thepressure receptacle connected therewith;

Fig. 4, a plan view of the same, and Fig. 5, a section on line OD Fig. 3, showing more clearly the means for securing the pressure receptacle to the said water pots.

awln the accompanying drawings, similar numerals of reference refer to similar parts throughout the several views and in which 1 designates a flanged elbow of a gas producer air pipe and which is provided with means for operating a valve 2, usually'found on such devices for admitting and closing air to the gas producer. 3 designates an additional part of the air pipe which is rigidly secured intermediate to the part 1 and the flanged elbow 4, thesaidpart 4 being rigidly secured to the gas producer 5. Air flows to said gas producer 5 upon the opening of the valve 2 through the parts 1, 3 and 4.

39 designates a boss on the lower part of theair pipe 3 and which has rigidly secured to it a water receptacle 6, which is adapted to retain water. Said boss 39 is provided with a plurality of apertures 8 communicating with the water receptacle 6 and to the inner part of the air pipe 3. The inner edge 9 of the aperture in the boss 39 is disposed lower than the edge 10, and water flows from the receptacle 6 through the apertures 8 and over the edge 9 through the air pipe 3 and 4 to the gas producer where it is vaporized and carried by the incoming air through the incandescent fuel in the gas producer.

12 designates the water supply pipe which openly terminates into the receptacle 6 below the apertures 8.

14 designates a by-pass connected to the pipe 12 and the air pipe 3., the function of said pipe 14 being to provide auxiliary outlet for the water in the pipe 12 in case the supply required is vgreater than can conveniently flow through the apertures 8,..and consequently filling of the pipe 12, also to provide additional means for the pressure in the air pipe to act on the pressure receptacle 24, hereinafter more fully described.

17 designates an outer water pot and 25 an inner one, integral with the outer, pot 17. Said; water pot 17 has a boss 31 extending from, the same and to which is secured, by threaded engagement, the pipe-12.

24 desi nates a pressure receptacle pro.- vided wit an open end which is inverted and immersed a predetermined depth in the water pct 25. Said pressure receptacle is provided with a plurality of wedge shaped cars 30 extending outwardly from same and adapted to engage, upon slight'turning, with gagement.

the area of the inlet 27. It is obvious that if wedge shaped cars 28 and 29 projecting inwar ly from the water pct 25. The space between the ears 28 and 29 forms a V-shaped opening which firmly secures the cars 30 upon engagement, and thereby rigidly secures the pressure receptacle 24 to the water pot 25, more clearly shown in Fig. 5.

18 designates a water supply pipe to the water pct 25 and the pressure receptacle 24, and 16 designates an overflow pipe from said water pot 17; water flowing over the edge of the pct 25 to the pct 17 when the demands for water to the producer is less than the amount flowing from the water supply pipe 18.

32 designates a pipe rigidly secured by threaded engagement to the boss 31 and which carries water from the pressure receptacle 24 to the pipe 12. Said-pipe 32 is provided on one side with a slot 33. In telescopic relation with said pipe 32 is an adjusta-ble pipe 22 which is secured in any desired position by a collar 21 secured by the set screw 20.

23 designates a cap for the pipe 22 and is rigidly secured thereto, by threaded en- Said pipe 22 is also provided with a slot 34 on one side and is adapted to alin'e with the slot 33. By traversing the pipe 22 upon the pipe 32 an adjustment of the opening for water from the pressure receptacle 24 tothe' pipe 32 is effected.

40 designates a set screw threaded into; the pipe 22, the projecting end of which engages with the slot 33 in the pipe 32 and; serves to preserve the alinement of the slots ducer. Unless air is admitted by some such 26 designates a casing having an inleti valve at 27 which is controlled by the screw valve 19. The amount of air entering the 33 and 34.

pressure receptacle through the inlet 27 is regulated by'the screw 19 adapted to vary the water sup 1y was continuous from the pipe 18 and at the water pressure receptacle had no atmospheric connection, such as the inlet 27, that upon the flow of water to the pipe 12 due to the suction of the producer, asiphonic action would be formed which would causena continuous flow of water which would render the device unautomatic and cause a detrimental eifect upon the gas supply due to the abnormal flow of water. The inlet 27 relieves this siphonic efiect from the supply to the discharge pipe and the water will consequently rise and fall depending upon the suction of the producer, thereby automatically regulating the quantity of water desired. 7

35 designates a transparent plate which is fitted to the pressure receptacle '24 and ceptacl e 24 by means of a band 36 secured to said pressure receptacle by the screws 37.

Having thus described the various parts throughout the several views its mode of operation will be substantially as follows: Water flows from the pipe 18 to the receptacle of the water pct 25 and then into the pressure receptacle 24 at the lower end thereof, the Water in the water pct 25 acts as an air seal to the pressure receptacle 24. Since the pressure receptacle 24 is directly connected to the air pipe of the gas pr0 ducer it is obvious that the pressure receptacle 24 varies in synchronism with the pressure in the air pipe dependent on the demands for gas from the producer. It is also obvious that although the pressure in said receptacle 24 varies in synchronism with the pressure in the air pipe that the pressure in the said receptacle 24 cannot equal the pressure in the air pipe unless the aperture 27 is completely closed by the set screw 19. Upon the opening of the aperture 27 to the pressure receptacle 24, a difference of pressure will exist between the pressure receptacle 24 and the air pipe to the gas producer on account of air being admitted to the pressure receptacle 24 through the adjustable apertures 27. As the pressure in the pressure receptacle 24 is a negative one, a varying partial vacuum will be formed dependent upon the suction of the gas producer, clue to the demand for gas, causing the water in the pressure receptacle 24 to rise and fall in synchronism with the varying demands for gas from the gas prodevice as the air inlet valve, a greater vacuum wlll be formed in the pressure receptacle 24, causing the water to rise to the top the pressure receptacle 24 rises and falls in synchronism with the pressure in the air pipe, thereby automatically regulating the amount of water admitted to the air pipe according to the demands for gas from the producer, and thereby accomplishing the hereinbefore first mentioned object of my said invention. It is also obvious that by raising or ,lcwerin the tube 22 and securing the same in any esired position by means oi? the collar 21 secured by the set screw 20, a manual regulation of the amount oi water admitted to the gas producer can be effected, thereby accomplishing the heretofore mentinned second object of my said invention It is found that upon sudden abnormal demands for gas from the producer the supply of water drawn through the water pipe-12 is more than can flow through the apertures 8 to the air pipe. A head of water will be formed in the water pipe 12 and which will rise until it reaches the height of the inlet of the by-pass pipe 14, when water will flow through said pipe 14 to the air supply pipe 3, thus relievin the water pipe 12 of the extra demand 0 water and accomplishing the hereinbefore mentioned third object of my said invention. Upon normal demands for gas from the gas producer, the head of water formed in the water pipe 12 will not normally reach the inlet of the by-pass pipe 14. It is then obvious that the pressure in said air pipe will be free to act on the pressure receptacle 24 through the by-pass pipe 14, and automatic regulation be effected, thereby accomplishing the hereinbefore fourth mentioned object of my said invention.

I do not wish to limit myself to the exact construction of the apparatus as shown and described as it is obvious that slight departures can be made therefrom without departing from the spirit and intent of my said invention, but

What I claim as new and desire to secure by Letters Patent, is

1. In a suction gas producer, the combination with a water pressure receptacle prov vided with means for admitting water below the normal water level therein and a discharge pipe from said receptacle to the producer whose outlet is above the inlet level of the supply, means integral with said pressure receptacle to prevent a siphon of the water from said supply to said discharge pipe.

2. In a suction gas producer, the combination with a water pressure receptacle provided with means for admitting water below the normal water level therein and a discharge pipe from said receptacle to the producer whose outlet is above the inlet level of the supply, an aperture in said pressure receptacle above the normal water level therein.

3. In a suction gas producer, the combination with a water pressure receptacle provided with means for admitting water below the normal water level therein and a discharge pipe from said receptacle to the proucer whose outlet is above the inlet level of the supply, an aperture in said pressure receptacle above the normal water level therein, and means to adjust the opening thereof.

4. In a gas producer, the combination with a water pressure receptacle connected thereto having the water supply inlet disposed below the discharge outlet to the producer, of an aperture in said receptacle located above the water level therein.

5. In a gas producer, the combination with a water pressure receptacle connected thereto having the water supply inlet disposed below the discharge outlet to the producer, of an aperture in said receptacle located above the normal water level therein, and means to adjust the opening of said aperture.

' 6. In a gas producer, the combination with a water pressure receptacle connected thereto having the water supply inlet disposed below the discharge outlet to the producer, of means to limit the discharge of water therefrom, an aperture insaid receptacle locatedabove the normal water level therein, and a means to adjust the opening of said aperture.

7. In a gas producer, an air pipe therefor, a water pressure receptacle havlng the water supply inlet disposed below the discharge outlet to the producer, said discharge water pipe communicating with said air pipe, an aperture in said water receptacle located above the normal water level therein, and means to adjust the opening of said aperture.

In testimony whereof, I have signedmy name to this specification in the presence of two subscribing witnesses.
